After the sliding strips areaccommodated in the sliding chutes of the base, the slider can slide onthe base along the sliding chutes. It is to be noted that, the slidingis bidirectional, that is, the slider can respectively slide to two endsof the base. After the slider slides for a certain distance relative tothe base, the elastic pieces located between the block pieces and theplates are compressed; and by releasing the slider, the elastic piecespush the slider to back to an original position.

As a further description for the technical solution of the presentinvention, with the electroplating treatment, an electroplating layer isformed on a surface of the slider and the base respectively and is usedto provide the better smoothness and reduce the noise.

As a further description for the technical solution of the presentinvention, the block pieces are located at the two ends of the base andare provided with a mounting hole respectively; the plates are extendedand bended from a top of the slider downwards; and a through hole isrespectively provided on the plates.

As a further description for the technical solution of the presentinvention, the connecting piece passes through the elastic pieces andthe through holes of the plates, and is fixedly mounted on the mountingholes of the block pieces. The connecting piece is mounted on the base,penetrates through the slider, and is configured to position and guidethe elastic pieces.

As a further description for the technical solution of the presentinvention, two plates are provided on the slider, and correspondingly,two elastic pieces are also provided. That is, one elastic piece isdisposed between the block piece on a left end of the base and one plateof the slider, and one elastic piece is further provided between theblock piece on a right end of the base and the other plate of theslider. With the connection between the two elastic pieces, the slideris available to slide to left and right relative to the base, and backto the original position automatically.

As a further description for the technical solution of the presentinvention, the connecting piece is a shaft which is cylindrical; theshaft passes through the elastic pieces and the through holes and isfixedly mounted on the mounting holes of the block pieces to positionand guide the elastic pieces.

As a further description for the technical solution of the presentinvention, the elastic pieces are springs. The springs provide arebounding force to the slider, so that the slider is available to backto the original position smoothly.

In conclusion, according to the sliding rail provided by the presentinvention, the slider is slidably connected to the base via the slidingconnection between the sliding strips and the sliding chutes, that is,the slider is available to slide to left and right relative to the base;and after the slider slides for a certain distance, the slider is pushedto the original position by the flexibility of the elastic pieces.

According to the sliding rail, because the sliding rail is with a smallsize, smooth and stable sliding process, low noise and an adjustablesliding force and sliding stroke as required, the sliding rail of thepresent application effectively improves the user experience of thesliding operation on the sliding rail.

Embodiment 1

FIG. 1 and FIG. 2 respectively illustrate an exploded diagram and anassembly finished product diagram of a sliding rail in this embodiment.Referring to FIG. 1 and FIG. 2, a sliding rail includes a base 1, aconnecting piece 2, elastic pieces 3 and a slider 4. The sliding rail isof a rectangular structure and uses the base 1 and the slider 4 as amain body structure. The base 1 and the slider 4 are subjected toelectroplating treatment, and have an electroplating layer on a surfacethereof. The connecting piece 2 and the elastic pieces are accommodatedin the base 1 and the slider 4. Correspondingly, the base 1 and theslider 4 are also of the rectangular structure. Two long edges of thebase 1 are bent upwards to form U-shaped sliding chutes 11 of the guiderail. Two short edges of the base 1 are protruded upwards and areprovided with a block piece 12 respectively. A mounting hole 121 isfurther provided on the block pieces 12. The mounting holes 121 on thetwo block pieces are located on a same straight line to mount theconnecting piece 2.

In this embodiment, the connecting piece 2 is a shaft which iscylindrical, and is used to position and guide the elastic pieces 3.

For combining with the base 1, a cross section of the slider 4 has aconvex structure which is corresponding to a cross section of the base1. The slider 4 comprises two long outer edges, a sliding strip 41 whichis arranged on each long outer edge, and the plates 42 which areextended and bended from a top of the slider 4 downwards. A through hole421 is provided on the plates 42 respectively. A diameter of eachthrough hole 421 is greater than a diameter of a cross section of theconnecting piece 2, and is smaller than a diameter of a cross section ofeach elastic piece.

In this embodiment, the plates 42 are extended and bent from a middle ofthe top of the slider 4 downwards, and respectively include a left plateand a right plate (not labeled in the figure).

The elastic pieces 3 are located between the block pieces 12 of the base1 and the plates 42 of the slider 4, corresponding to the left plate andthe right plate of the slider. The elastic pieces include a first spring31 on a left side and a second spring 32 on a right side.

About the connection between every components, first of all, theconnecting piece 2 which is located inside passes through the firstspring 31 and the plates 42 (a left plate and a right paddle) of theslider 4 in sequence, and are fixedly mounted on the mounting holes 121of the block pieces 12. Meanwhile, the sliding strips 41 of the slider 4are accommodated in the sliding chutes 11, and slides on the base 1along the sliding chutes 11. It is to be noted that the slider 4 isavailable to respectively slide to left end and right end of the base 1along the sliding chutes 11.

By pushing the slider 4 to slide to the right end of the base 1, whenthe slider 4 slides for a certain distance, which means the slider 4 isnot at the original position, the second spring 32 is compressed; andafter releasing the slider 4, the second spring 32 pushes the slider toslide to the left and automatically back to an original position. Bypushing the slider 4 to slide to the left end of the base 1, when theslider 4 slides for a certain distance, which means the slider 4 is notat the original position, the first spring 31 is compressed; and afterreleasing the slider 4, the first spring 31 pushes the slider to slideto the right and automatically back to the original position.

In this embodiment, the base and the slider are subjected toelectroplating treatment, so that an electroplating layer is formed on asurface of the slider and the base respectively. When the slider slidesto left and right on the base, because of the sliding connection betweenthe sliding strips and the sliding chutes, the better smoothness isobtained and the noise is reduced.

According to the sliding rail in this embodiment, because the slidingrail is with a small size, smooth and stable sliding process, low noiseand an adjustable sliding force and sliding stroke as required, thesliding rail of the present application effectively improves the userexperience of the sliding operation on the sliding rail.

The above contents are merely examples and explanations for thestructure of the present invention, and the description is specific anddetailed but cannot be understood as a limit to the patent scope of thepresent invention thereto. It is to be noted that those of ordinaryskill in the art may further make a plurality of variations andimprovements without departing from the concept of the present inventionand these obvious replacement forms all pertain to the protection scopeof the present invention.
